Product Overview

The Armaflex Plain Insulation Sheet/Roll (14m x 1m x 12.5mm) is a premium closed-cell elastomeric insulation material engineered to deliver reliable thermal protection, condensation control, and long-term energy savings. With its 12.5mm (1/2″) thickness, this roll is ideal for medium-temperature insulation needs such as chilled water pipes, AC ducting, refrigeration lines, and hot water systems.

Manufactured from high-quality nitrile rubber, this Armaflex roll offers excellent flexibility, low thermal conductivity, and outstanding moisture resistance. Its closed-cell structure eliminates the risk of water absorption, preventing corrosion under insulation (CUI), mold growth, and efficiency loss—making it the preferred insulation for commercial, industrial, and residential installations.
